Fig. 1 is please referred to, the present embodiment provides a kind of piercing assemblies 010 comprising puncture needle 200 and angle guide instrument 100,
The angle guide instrument 100 is connect with puncture needle 200；Entry point when the puncture that medical worker measures according to CT surface sweeping etc. is to suffering from
After the distance and angle of person's lesion, using being set to the angle guide instrument 100 of puncture needle 200 according to the angle inserting needle measured, and
The angle that angle guide instrument 100 is shown when inserting needle is exactly that the needle angle of puncture needle 200 so can use angle
Guide instrument 100 improves the accuracy of the needle angle of puncture needle 200, and is no longer to determine puncture according to the experience of operator
Angle.
Further, referring to figure 2., the angle guide instrument 100 of the present embodiment includes positioning disk 110 and ring pipe 120, ring
Shape pipe 120 is sheathed on the periphery of positioning disk 110, and the inside of ring pipe 120 has liquid storage chamber 130, and liquid storage chamber 130 is along ring pipe
120 circumferentially extending, liquid storage chamber 130 is for storing marking liquid 131；First face of positioning disk 110 is provided with multiple scales, more
A scale is circumferentially distributed along positioning disk 110.It should be noted that the liquid storage chamber 130 in ring pipe 120 contains marking liquid
When 131, the liquid storage chamber 130 of ring pipe 120 cannot be filled up, segment space should be flowed out in the liquid storage chamber 130 of ring pipe 120
It can be in the liquid storage chamber 130 of ring pipe 120 around the circumferential flow of ring pipe 120 convenient for marking liquid 131.When angle guide instrument
When 100 angle deflects, the marking liquid 131 for being stored in ring pipe 120 can flow in the liquid storage chamber 130 of ring pipe 120
It is dynamic, and contain and be oriented to the meeting of the first end liquid level 132 and second end liquid level 133 of the marking liquid 131 of ring pipe 120 according to angle
The corresponding scale different from positioning disk 110 of the deflection of the angle of instrument 100.
It should be noted that multiple scales on positioning disk 110 can be used to indicate that different angles, when angle guide instrument
100 deflect, and the marking liquid 131 in ring pipe 120 is in ring pipe 120 around the circumferential flow of ring pipe 120, identification liquid
The angle that the corresponding scale of the liquid level of body 131 represents can be considered angle guide instrument 100 and be provided with the angle guide instrument
The deflection angle of 100 puncture needle 200.
Preferably, the volume for the marking liquid 131 stored in the storage chamber of the ring pipe 120 of the present embodiment is liquid storage chamber
The half of 130 solvent, so, the both ends liquid level of the marking liquid 131 held in ring pipe 120 are in horizontal always
Be located at same level, two scales of the corresponding positioning disk 110 of the both ends liquid level of marking liquid 131 represent identical
Angle, when the angle of the angle guide instrument 100 deflects, the marking liquid 131 in ring pipe 120 is in ring pipe 120
